So I just finished Kotor 1 and while talking to Canderous, he told an intersting story. Remember when he told him about the time he was playing with smugglers, and when he hit some rock or gas cloud, and something old and powerful showed up. Something fast, with hude firepower, and in the end it fled to dark spece. A Reaper! Well maby not, but it sounded like one.

Honestly, I think Mass Effect was BioWare's "unofficial" take on a KotOR sequel. I mean, the idea of the Reapers is kind of analogous to the True Sith - an enemy much larger than anything the known galaxy has ever seen before.
